The computer does not belong to a valid Active Directory site. Check the site and subnet definitions.

The computer has been removed and re-added to AD. Intstallation works fine on other non-virtual machines at this location/subnet. Any ideas on what to try next?

We have checked the firewall and AV and nothing seems to indicate those are the issues.

What is interesting is that a packet capture during the installation shows a lot of traffic to/from 207.46.19.190. This is a Microsoft website. There are a lot of RST packets before the error message shows during the install.
